Someone educate me: Why can't he just bump Dunn and Hammer up to 3/4 and bat Guzman lower? Or even put Guzman back in the two hole? I've defended Guzman but even I would agree he's not a 3-hitter.
My inner geek says that 3d is a less important spot in the order than 4th and maybe 5th, and you want a guy who both draws walks and has power hitting 4th. Next to leadoff, 4th actually leads off innings more than any other position. 3d most frequently comes up with 2 outs and no one on. Walks aren't as useful there, so the guy who is allergic to walks and makes contact makes some sense.
Having said that, I'd prefer Pudge there. I am getting a bit tired of babying Guzman. Lefty Guzman does not seem all that effective. I'd make the SOB bat 6th and like it. Finally, I might even think of trying the old "pitcher 8th" trick with Olsen and put Kennedy 9th and Willie 2d.
